JOHN S. BARNES, OF ROCKFORD, ILLINOIS, ASSIGNOR TO W. F. & JOHN BARNES COMPANY, OF ROCKFORD, ILLINOIS, A CORPORATION OF ILLINOIS.

SPEED-GEARING.

1'0 all whom it may concern:

Be it known that I, JOHN S. BARNES, a

citizen of the United States, residing at Rockford, 1n the county of \Vmnebago and State of Illinois, have invented certain new and useful Improvements in Speed-Gea1-ing,

' has a driving pulley 6 connected therewith,

and the spur gears 7 and S loosely mounted on it and provided with clutch faces 9 and 10 respectively, and the shaft 3 has two spur gears 11,and 12 fixedly connected to it. The shaft a has two spur gears 15 and 14k fixedly connected to it and has two spur gears 15 and 16 loosely mounted on it. These spur ears 15 and 16 are provided with clutch faces 17 and 18 respectively. The shaft has two spur gears 19 and 20 loosely mounted on it, and provided'with clutch faces 21 and 22 respectively. The loosely mounted spur gears are held in position on their shafts by the collars 23 pinned to the shafts. The shaft 2 has a double clutch section 24 splined .to it and is adapted to be moved in engagement with the clutch faces'9 and of the spur gears 7 and 8. The shaft 4 has a double clutch section 25 splined toit and is adapted to be moved in engagement with the clutch faces 17 and 18 of the spur gears andlG. The shaft 5 has a double clutch section 26 splinedto it and is adapted to be moved in engagement with the clutch faces 21 and 22' of the spur gears 19 and 20. The

shaft 5 has one end projecting beyond theframe and to which is pinned a hovel pinion 27. A shaft 28 issnpported-by a bearing in the frame I, and has a bevel gear 25) pinned to it. The bevelv pinion 27 and bevel gear 2!) are in mesh. The spur gear 7 is in mesh with the spur gears 11 and 15, and the spur gear 8 .is in mesh with the spur gears 12 and 16. The spur in mesh, and the spur in mesh.

\Vhen thedouble clutch sections are free gears 13 and19 are gears 14 and are Specification of Letters Patent.

of engagement with any of the clutch faces of any of the spur gears, the shafts 3, 4 and 5 will remain at rest, and the shaft 2 will be the only one in motion. By moving. the double clutch section 24: into engagement with the clutch face of the spur gear 7 the spur gear 7 will be rotated which will rotate the spur gears 11 and 15, and also rotate the spur gears 12, S and 16. By moving the double clutch section inte -engagement with the revolving spur gear 15, the shaft 1 will be rotated which will'rotate the spur gears lthond 20 on the shaft 5. By moving the double clutch section 26 into engagement with first one and then the other of the revolving spur gears 19 and 20, two speeds will be given to the shaft 5 and through the bevel gears to the driven shaft 28. By IITOI x ing the double clutch section 25 into engagement with the revolving spur gear "16 the shaft a l will be revolved hta different speed which will revolve the spur gears 19 and 20 at different speeds and tl'n'ough the double clutch section 26 twoother speeds will be given to the driven shaft.

By moving the double clutch section 2 1 into engagement with the face of the spur gear 8, and moving the double clutch section 25 alternately, into engagement with the spur gears 15 and 16, and moving the double clutch section 26 alternately into engagement with the spur gears 19 and 20 four more different speeds will be imparted to the driven shaft, making in all eight different I speeds that can be imparted to the driven shaft 28 from a given speed imparted to the driving shaft.

The uses to which this speed gearing-can be applied are various, and especially in the machinery line.

I claim as my invention: 1. A variable speed gearing comprising a driving shaft, two spur gears loosely m0unted on the shaft and each provided with a clutch face, adouble'clutch section splined to the shaft and adapted to engage the clutch faces of the spur gears, another shaft, two spur gears fixedly connected thereto and meshing with the spur gears onthe driving shaft, anothershaft, two spur gears loosely mounted on this shaft and. each n'ovhhal with a clutch face, adouble clutch section splined to the last mentioned shaft and adapted to engage the clutch faces of said spur gears, the last mentioned spur gears meshing with the spur gears on the driving shaft, a driven shaft, and a driving connection between the last mentioned shaft and the driven shaft.

2. A variable speed gearing comprising a driving shaft, two s ur gears loosely mounted on the shaft an the shaft and adapted to engage the clutch faces of the spur gears, another shaft, two

spurgears fixedly connected thereto and meshing with the spur gears on the driving shaft, another shaft, two spur gears loosely mounted on this shaft and each provided with a clutch face, two spur gears fixedly connected with the shaft, a double clutch section splined to thelast mentioned shaft and adapted to engage the clutch faces of said spur gears, the last mentioned spur each provided with a v clutch face, a double clutch section splined to gears meshing with the spur gears on the my hand in presence of two subscribing wit- DGSSGS.
